My 1.6 tdi had an overheating problem about a month ago. Temperature would go over 90 to about 100 when going up hill. No loss of coolant, no lack of heat from the interior heater, no loss of mpg or power, no fault codes. I got the waterpump and timing belt replaced and has been fine since for about 700 miles. However the fan seems to be on most times when at 90 (was like that when I got it in May)

However today it developed the same symptoms while driving, a bit jerky taking off/rough running etc. And when going up hill the temperature had rise again, the fan does come on but possibly I think it comes on when it is too late.

Any body have a problem like this before? Or where would I start with it having no fault codes

What about the thermostat,has that been changed ??

- Check coolant level

- Check water pump is still pushing water into the expansion bottle

- Check thermostat isn't jammed

 

My wife's Fabia has overheated slightly a couple of times, and it's been when it was doing a regen when stuck in traffic, the water temp went up to around 100-110. I put the fan on hot and it soon cooled down and was fine when we got moving. It does also run noticeably rougher when doing a regen (no fix here! )

Cheers for the replies, but after further research it sounds like the car has had the emissions 'fix' which is causing problems. Will contact vw tomorrow
